Hello, recently i have been experiencing some difficulties with Minecraft Forge. I downloaded the recommended 1.7.10 Installer, installed the client and started up Minecraft in that profile. The trouble is, every time I click play, the launcher closes and there is no second window popping up with the startup screen. Unfortunately, I didn't recieve a crash report so I can't share one with you guys. I have deleted my .minecraft a couple times now, it doesnt do any good. I hope you might be able to help me to diagnose the problem and solve it. Any help is greatly appreciated, thanks!
It happend to me too, and tried to download another versions of forge but did't work, what is more, now my launcher says "version 1.5.2" insted of "1.7.10" i don't know if this will bring me any problem, but i don't know how to restore it back to 1.7.10, i tried putting edit profile to latest version, but it only affects minecraft when the game launches, but not the launcher it self.
So a little help with the launcher and the forge problem would be appreciated
How exactly do i get the game output?
Here, this might shed some more light on it. This is my fml -client lastest log
